In the end we all die of heart failure. Why the heart failed is the issue and usually only a autopsy can determine that. If they are doing an autopsy it is usually quite some time before results are released.

Being fit certainly moves you out of the category of heart problems that usually effect the overweight but it can put you into the category of unexpected failures like aneurysms. In any case I hope he didn't suffer and passed peacefully as all of us hope to do.

Lawrence, my condolences to you and the others that had him in their lives. Is there an obituary? If so could you post a link?

Orbit in Palatine, IL? Google is saying 6h and change from here... I'm not ruling that out, who is going?
